No diodes, just gas-tube for large surge event suppression. Obviously
not as much protection though. I'm seeing more CRC errors than I'm
comfortable with on the cards with diodes. Rev G is definitely better
though. I've broken the shield at various sites while testing to rule
out any potential ground loop issues. Ran on battery. Etc. It's weird.
Noise or something, I don't know.

Thanks, yeah nothing fit well next to the thin pcbs.
Odd, got some test results back from George yesterday. Some types of
equipment has CRC errors with some of our surge suppressors.
Trying to
identify the bad combinations. Good thing is that our gas tube only
products seem to be flawless with everything that people have
tried them on.

Chuck,
Like form factor of new arrestors much better. Thicker PCB and RJ45
not as tall. They do not fit well next to your last thin pcb version
though. Did not care for the thin pcb and tall RJ45 at all. Swapped
out 4 PxP450i APC arrestors to these 17 hours ago. So far flawless
even at 1000base. No errors at all. This is with RackInjector,
Cambium Sync and very long cat-5 runs. Time will tell but looks good
so far.
